What Are These Expired Entries In Manage SSL Hosts?

In WHM -> SSL/TLS -> Manage SSL Hosts in the Installed SSL Hosts section I have several entries for:

Code:

autoconfig.*
autodiscover.*
cpanel.*
cpcalendars.*
cpcontacts.*
host.mydomain.com
webdisk.*
webmail.*
whm.*

where "host.mydomain.com" is my host name. There's one of these entries for each IP address on the server, including one for 127.0.0.1. All of them show a certificate expiration date of 1/1/70. I have a private SSL installed for the host services (Service Configuration -> Manage Service SSL Certificates) that is up-to-date.

Are those entries serving any purpose? Is it safe to delete them?

 

Thanks, Michael.
